For freshman/sophomore-level courses in Introductory Soil Science or Earth Science. Extensively class-tested, this lab manual provides a hands-on introduction to basic principles of soil science - with a focus on the natural properties and processes that govern soil. Contemporary and practical in perspective, it emphasizes factor analysis throughout and makes extensive use of the World Wide Web for gathering the most up-to-date data. This lab manual will accompany all three of PH's texts: Brady, Miller, and Singer.
